COTTON-PRESS.

Specification of Letters Patent.

Patented July 20, 1909.

Application filed May 23, 1907. Serial No. 372,309.

To all whom it may concern:

Be it known that l, BUROl-IARD TIIOEN s, a subject of the Emperor ofGermany, and resident of the city, county, and State of. New York, haveinvented certain new and useful Improvements in Cotton-Presses, of whichthe following is a specification.

My improvement applies. especially to roller presses and in theaccompanying drawing my invention is shown in connection with a press ofthe character shown in Letters Patent No. 759,386.

Referring to said drawing, Figure 1 is a sectional elevation ofsufficient of such press to illustrate my invention; Fig. 2 a partialview showing certain elements in a different position; Fig. 3 a detachedview showing a modification.

Roller presses of the class shown in the said patent bale cotton byfolding a bat in layers on a receding platen of a hydraulic press. Theexisting defect of this type of presses consists in the fact that itmakes the folds very irregular, at some strokes it makes no fold at all,because the cotton is moving away from the rollers at the same speed asthe rollers advance. If these rollers are smooth, they simply push thecotton away. To overcome this defect I provide means whereby at the endof each traverse of the rolls and as they begin the return movement thebat is positively folded and the fold laid in exact position.

In the construction shown in the drawing, cotton is introduced in asuitable hopper a, passing down between throat-irons 0, 0, and throughthe central space between the central rollers cl, (5, supported by thecarrier A and reciprocatingover the surface of the platen e of asuitable hydraulic lifting press The whole machine consists ofpartsmounted on a suitable frame and driven in suitable manner (notshown) to reciprocate the carriage and rotate the rollers. Blades g, g,are suspended outside the throat irons c from the ends of levers h hfastened to rock shafts i, 2'. To the same shafts z, i, are fastenedlevers j, j, on the ends of which are mounted rollers 70, 72, moved andguided in a groove of a stationary guide frame Z. Near the ends of thegroove in the frame Z are hung switches m, m, which allow the rollers70, is, to pass under the switches m, m, when moving in one direction,but compel the rollers 72, 7a, to rise and pass over them when moving inthe opposite direction. In Fig. 3 is shown a modification in which aswitch a is heldup by a spring 0 to aline with a rib p in one positionbut to yield to permit the roller, passing below the ri to move betwecnthe latter and the switch on moving in the opposite. direction.

The operation of my device is as follows: The carriage and its rollersbeing reciprocated, the blades 9 are held in a vertical or elevatedposition during the stroke, but its lower edge is brought against theupper cotton is pushed under the other roller cl thereby positivelymaking a fold; the blade is then withdrawn.

it will be evident that while I have shown certain appliances foractuating the folding means, as the blades 9, the actuating means may bevaried to a great extent, it being required only to carry the edge of ablade across the bat at the end of each traverse of the carriage and itsrolls, and hold the bat on the mass below until the advancing rollengages the fold and presses it onto the mass, whereby the folds are alllaid in the same vertical plane at each side of the mass.

lVithout limiting myself to the construction and arrangement shown, Iclaim,

1. In a cotton press provided with a recip rocating carriage andbatfeeding means and movable bale support, means supported by thecarriage for holding the upper bat layer in position at the side of thebale at the beginning of each return movement of the bat, and means foractuating said holding means.

2. The combination in a press, with a re ciprocating carriage, a seriesof rollers carried thereby, and means for conducting a bat of cottonbetween two of the rollers, of

means supported on the carriage for holding the upper bat layer upon themass below prior to each return movement of the carriagc, and until thefold is under pressure by the returning roller.

8. The combination in a press, with a re ciprocating carriage, a seriesof rollers carried thereby, and means for conducting a bat of cottonbetween two of the rollers, of blades supported adjacent to the bat,supports for the blades on the carriage and means for operating thesupports and blades to press the bat upon the mass below prior to eachreturn movement of the carriage, and for thereafter withdrawingtheblade.

4. The combination in a press, with a reciprocating carriage, a seriesof rollers carried thereby, and means for conducting a bat ofcottonbetween two of the rollers, of rocksh'afts carried by the carriage andprovided with arms and blades 9 pendent there from between the centralrollers, and means for rocking the shafts to bring the edges of theblades upon the upper layer of the bat adjacent to the side of the baleprior to each return movement ofthe carriage.

5. The combination with the frame reciprocating carriage, and rollers ofa cotton press, of rock shafts on the carriage provided with arms andblades pendent therefrom between central rolls, other arn1s of the shaftprovided with side rollers or projections 70, and guide grooves andswitches upon the frame arranged to act on said rollers is to rock theshafts to bring the edge of the blade upon the upper layer of the batprior to each return movement of the carrlagc.

In testimony whereof I affix my signature in presence of two witnesses.
